If you prefer to feed your dog eggs that have been cooked you can boil or scramble them. Some fatty acids and fat soluble vitamins will be lost to the cooking process as well as various proteins. But the overall impact of the eggs will still be more beneficial than no eggs whatsoever.

For a large dog, such as a Rottweiler, an egg per day is a great addition to any diet. More can be given to pregnant or lactating bitches; less for young puppies or smaller breeds. The amount of eggs to feed is very dependent on the individual dog. Eggs are very rich and should be introduced slowly to your dog's diet. Some dogs will tolerate them well and enjoy several, where others will need fewer and only a couple per week. Eggs are a fantastic, well rounded, "mother nature's perfect food" addition to first foods for a litter of puppies. For puppies just learning to eat solid foods scrambled eggs are a great place to start.

Great book with some info on feeding eggs:

A note from the author: Raw Feeding is a big topic and everyone disagrees on how to go about it. Talk to your vet who may very well say, "don't you dare, here's some Hill's Science AKA CRAP," (I added that last part for flair) read all of the articles you can find, and study all of the books you can get your hands on. Start slow, introduce foods gradually and one at a time. Don't let anyone discourage you. Feed what your dog likes, what he or she will eat, and what is available to you. Additives should be fed in moderation. But remember, variety is key to obtaining all their necessary vitamins and minerals. There isn't a lot of profit in studying raw diets for dogs so very little is known with absolute certainty.
